RDS 2012 - Using a reverse proxy with the Gateway server on the internal LAN

Hi there,
I'm looking to introduce an RDS 2012 farm and would like to put the RDS Gateway server on the internal LAN (due to it's AD requirements etc).
What are the best practise options for using a reverse proxy to forward traffic to the gateway server and is it better to do this than just forward 443 traffic from the DMZ through to the Gateway directly?
Thanks,
Paul.

Hi Paul,
It is generally considered more secure to have a reverse proxy in front of RDG. I don't know of a proxy that will handle the RDG UDP traffic, so you will need to consider using direct server return for that or not having the benefit of UDP. Whether
or not it is acceptable to simply forward TCP 443/UDP 3391 directly to your internal RDG is up to your security policies. Many companies are fine with it while many other companies think it is unacceptable and require a reverse proxy or other method
to provide an extra layer of protection.

Reverse Proxy with Sun Web Server 7 update 4

Hi All,
I've just migrating to Sun Java System Web Server 7.0U4 B12/02/2008 from Sun Java System Web Server 7.0-Technology-Preview-3 B09/13/2006. I've have the two web servers running side by side on separate machines. Both have a VS configured as a reverse proxy pointing to the same apache tomcat web server.
The Tech Preview 3 server works fine and has been doing since it was installed. However the Update 4 server doesn't. I can access the tomcat app via the U4 server in a browser, but not with the app on my mobile (sync ML). Snooping the traffic show me that the U4 server is sending a different response that the Tech Preview server. I'm thinking it may have to do with Transfer Encoding: chunked. I've looked around the web to see if I can turn this off in the U4 server, as I seem to recall having to do so at some point in my life, though I can't remember when and with what.
Does anybody have any clues they can throw at me?? Or anybody know what has change in the reverse proxy part of the web server from Tech Preview 3 to U4??
Both VS reverse proxies are congfigured exactly the same.
Thanks,
Stuart.

well, technology preview is what the name says .. i am surprised that u decided to stick with a technology preview release all these days.. in any case, there should not have any feature change between technology preview build and U4. but , there has been lot of bug fixes - so, unless we know the exact problem - we can't easily narrow down the change between tp3 build with U4 and find out how it is affecting u.
here is a related article on how to use chunked encoding within web server 7
http://developers.sun.com/webtier/reference/techart/chunked_req.html
now, to help you more appropriately, you need to provide us with errors (probably with log level set to finest within server.xml) and let us know with the error reported by web server when it is unable to send those requests to back end tomcat
you can set log level to finest by running the following command
/sun/webserver7/bin/wadm set-config-prop -user=admin --config=<hostname> log-level=finest
/sun/webserver7/bin/wadm deploy-config --user=admin <hostname>
http://docs.sun.com/app/docs/doc/820-4842/set-config-prop-1?a=view
(once you have identified the problem, you might want to set log level to info as setting to finest will cause your logs to grow humongous and also hurt performance

HT3382 With a MacbookAir (mid-2012) using a mini DisplayPort to VGA adapter plugged into the Thunderbolt port, can you configure the external monitor to FULLY display in portrait mode yet keep the built-in display in landscape mode?

With an 11"-inch Macbook Air (mid-2012) using a mini DisplayPort-to-VGA adapter plugged into the Thunderbolt port:
Can you configure an extended desktop with an external monitor (20") displaying full portrait mode (1200 x 1600 resolution) and keep the built-in display in landscape?
I'd like to see something like
External monitor / Built-in display

Yes, I can't see why not.
Just give it a try and report back if you have a problem.

Applet does not load using java 1.5 through reverse proxy with certific...

Hi,
we have the following problem:
When using java 1.5 in our browser, our applet does not load. Using java 1.4.2 it works. It also works using java 1.5.0 using another reverse proxy.
The differences between the 2 reverse proxies (one works, one works not) we use is that the one through which the applet does not load has a certificate installed that is not for its hostname. Can this be the reason the applet does not load? Where can I find information about the sandbox of java 1.5.0 concerning these issues. Are there any docs of the security restrictions imposed by java 1.5.0 sandbox?
Greetings,
Tim

Ok,
the solution to this specific problem was a misconfigured reverse dns lookup.

IIS Reverse Proxy with URL rewrite.

Hi all, hoping to leverage the wealth of knowledge contained here.
Any assistance would be very welcome.
I'm having an issue getting a reverse proxy and URL rewrite working in IIS 7.0.
I need to redirect all requests with a specific virtual directory suffix only.
ie; https://domain.test.com/outbound/Content/query_etc
With /Outbound/ being the trigger.
This should be redirected to http://10.10.10.10/inbound/Content/query_etc
While at the same time, requests without the /outbound/ suffix should be handled locally.
I have configured the reverse proxy as described in a few articles, and have had no luck.
Here's a snippet from my (sanitized) web.config at the site level.
<rewrite>
<outboundRules>
<rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml1">
<match filterByTags="A" pattern="^http(s)?://10.10.10.10/inbound/(.*)" />
<action type="Rewrite" value="https://domain.test.com/outbound/{R:2}" />
</rule>
<preConditions>
<preCondition name="ResponseIsHtml1">
<add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
</preCondition>
</preConditions>
</outboundRules>
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="^outbound/(.*)" />
<action type="Rewrite" url="http://10.10.10.10/inbound/{R:1}" appendQueryString="true" logRewrittenUrl="false" />
</rule>
</rules>
</rewrite>
To me, this looks correct, yet it doesn't work.
With this, I get the normal 404 - Error Code 0x80070002, with the text indicating the local directory doesn't exist, so.... not being picked up by the filter for redirection.

Hi Andrew,
Looking at your requirements it appears you need Reverse Proxy To Another Site/Server.
By using URL Rewrite Module together with
Application Request Routing module you can have IIS 7 act as a
reverse proxy.
It seems like URL Rewrite can't re-route the request somewhere else out of the server.
Even when you rewrite the url the actual connection remains with the server. Hence if your original server doesn't have /inbound/Content/query_etc it will fail with 404.
Hosting multiple domain names under a single account using URL Rewrite.
It’s a common desire to have a single IIS website that handles multiple sites with different domain names.

BizTalk published WCF service throwing HTTP 404 error using ISA reverse proxy settings

I have published my schemas as a WCF service from BizTalk 2010 "Publish WCF Service" wizard. I used Wcf-basicHTTP adapter in receive port. I am able to run the service successfully on localhost IIS and I tested my biztalk solution by sending request using SOAP UI and got response successfully.... Now: Actually, I need to give this service endpoint to my vendor who will send request from outside my company's network i.e. internet. In my infrastrucrue BizTalk is behind the firewall so, we setup a REVERSE proxy server at DMZ layer and it is configured properly. I have tested a simple WCF service by replacing the localhost with Proxy server configured address <DNSName> and it worked absolutely fine. But when I change localhost in my BizTalk schema based published WCF service it is not working and I am getting following error. Really strugling to get it resolved. I wasted a whole 3 days....very upset. Please help me out by giving the detailed step solution. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /BizTalkServiceInstance/MyService.svc I am surprized why other c# code based WCF services are working fine with reverse proxy settings. Server Error in '/' Application. The resource cannot be found.Is there any special things to consider Biztalk exposed wcf servcie over ssl in IIS cluster with ISA

Hi Singam :)
First I would start by browsing any other files (files other than the one from WCF) just to ensure that the reverse-proxy’s redirection rules are set correctly. If you get the same 404 error when you try to access other service/files “through reverse-proxy”,
then it’s an issue in the redirection rule(s) in reverse-proxy.
If others are fine i.e. no issue in reverse-proxy setup as such, then try the following for WCF service's web.config file. I have seen this issue in WCF service (not just BizTalk’s artifacts exposed as service in reverse-proxy). Add serviceHostingEnvironment
config as show with in serviceModel section.
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>

Reverse proxy with apache2

Hi folks,
I have a huge problem here. I have a apache 2.0.50 on a Linux system that is to act as a reverse proxy for an enterprise portal. I have set up the apache to do reverse proxying and so far I have made first success. I can get to the login page of the portal and I even managed to make it show the images. The problem is, when I try to log on to the portal I am always send back to the logon page in the very instance. If I enter the wrong logon information I see the authorization failed text, but when I enter correct information I only see the logon page again.
I will put tyhe relevant part of my httpd.conf to this message and hope someone can point me to the right location or maybe even tell me what I'm doing wrong.
And ny the way, the portal itself works perfectky when connected directly.
Kind regards,
   Christian Guenther

Apache Reverse Proxy with Abap Web query

Hi to all
We are trying to configure apache 2 to work as a reverse proxy with web abap Netweaver installation.
From inside the network the web query is fine.
Running the query with the reverse proxy we have only the html code in the browser. All the scripts and css are not present.
We checked some messages inside the forum and we have tried a lot of stuff without success.
We use always linux (Fedora, Ubuntu with xampp or apache only) plus the html module or the publisher from http://apache.webthing.com.
Our installation is like this the reverse proxy in the dmz and the netweaver to the inside off coarse, and we don't have the same domain name, i don't know if this is important.
Any help/idea is valuable.
Thank you
Yiannis

Hi Olivier
I have seen your solution in other messages but i didn't try it because i was trying to work with the html_proxy module.
I read the documents you gave me plus some apache tutorials on the rewrite rule.
In any case i have my installation working now.
I did some extra changes in my config so now the rules are like that
ProxyVia On
ProxyBadHeader IsError
ProxyRequests Off
ProxyPreserveHost On
ProxyPass /sap http://192.168.1.59:8001/sap
ProxyPassReverse /sap http://192.168.1.59:8001/sap
RewriteEngine On
RewriteRule ^/(sap\(.*) http://192.168.1.59:8001/$1 [P,L]
Thanks again for your help

OCS on a single computer / DMZ using Apache reverse proxy

Hi there,
we've installed the OCS 10.1.2 on a single Solaris box in our internal LAN. Everything works fine internally. We would like to configure a Apache reverse proxy in our DMZ to get the possibility to use it from outside (as shown in "Oracle Collaboration Suite Deployment Guide", chapter 3, Figure 3-2 Single Computer in a DMZ). Unfortunately I didn't find any configuration hints for the reverse proxy.
Can someone provide me with an example configuration?
Thanks,
Christoph

Hello Andreas and Christoph!
I have the same problem like Christoph. We made a Singlebox-Installation of OCS 10.1.2 in the intranet. Now I am looking for installation documentation, how I have to configure a Apache or Oracle Standalone Webcache as a reverseproxy in the DMZ. to allow access the OCS from the internet. I only read, that it is possible, but nothing about the way.
I have installed a Webcache (OAS 10.1.2 Java Edition not dht standalone Veersion from the Companion CD) and configured by my own knowledge. The result was network errors.
Is there anywhere information?
Best regards!

First you have to know what you are doing, like an engineer : you have a
Laplace, continuous time transfer function but LabView handles discrete
signals only. Use matlab/simulink if you want to simulate continuous time
systems easily...
If you definitely want to use LabView, the first step is to discretize your
continuous-time transfer function, i.e. decide a sampling rate and convert
it to a "z transfor
m". Then you can directly use the "IIR Filter.vi" as I
said earlier.

I use an iPad 3 with IOS6. When opening the calendar and strolling to MARCH 2013 calender shuts down...
Anybody with same problem or having a solution?

Try removing any all-day events from the calendar for the 1st April 2013 e.g. if you are syncing the calendar from somewhere else (e.g. Outlook on a PC or iCal/Calendar on a Mac) then change it to a timed event instead of all-day - it seems that there is a problem with all day events on that date which is when the clocks change due to daylight saving.

Hi,
Same physical printer but when connecting to SAME computer using both USB and wireless it becomes two (logical) printers. Probably your default prnter is the wireless one, you have to select the right printer before print .
